Adding cold brew to your range sounds straightforward enough. You’ve already roasted the coffee. You have the customer base. The branding is sorted. The part that catches most roasters off guard is the packaging.
Cold brew behaves differently from ground coffee or whole beans. It’s liquid-adjacent at best, fully liquid at worst, and the packaging decisions that follow are genuinely different to anything you’ve dealt with before. The barrier properties that matter change. The seal requirements are higher. And the format you choose has real consequences for shelf life and how the product reads on the shelf.
This guide walks through the key decisions involved in choosing cold brew coffee bags and packaging that protects the product and represents the brand properly.
Cold brew packaging is a different problem from roasted coffee
When you package roasted beans or ground coffee, the main job is to keep oxygen out and let carbon dioxide escape. A good foil bag with a one-way degassing valve handles that well.
Cold brew changes the brief.
Whether you’re selling a concentrate, a ready-to-drink product, or a steep bag that customers brew themselves in cold water, the packaging is dealing with moisture in a way a standard coffee bag never has to. Even cold brew steep bags, which are a dry product, sit in contact with cold water for eight to twelve hours during brewing. The outer packaging needs to account for where the product ends up, how it’s handled, and what it has to survive before it reaches the customer.
Get the material wrong, and shelf life suffers. Get the seal wrong, and the product fails before anyone gets to taste it.
The format question comes first
Before you choose a material, determine the form your cold brew product actually takes. The answer changes everything downstream.
There are three common formats:
Cold brew concentrate
A liquid product, typically sold in a sealed flexible pouch. High barrier requirements. Needs a clean, consistent heat seal because the contents are under pressure and any weakness shows quickly.
Ready-to-drink cold brew
Single-serve, sealed, consumed directly. RTD cold brew in a rigid bottle or can sits outside what a flexible packaging printer handles, so this guide focuses on the pouch and bag formats where flexibility is relevant to your decision.
Cold brew steep bags
A dry product, similar in concept to a tea bag. Customers place the bag in cold water and brew it in the fridge overnight (or longer). The packaging is a sealed outer pouch that keeps the steep bag fresh until it’s opened.
The steep bag and concentrate pouch formats are where most small roasters start. Both are well within scope for short-run printed packaging, and both reward careful material and feature choices.
What to look for in a cold brew coffee bag
Once the format is settled, here are the features worth considering before you place an order.
Barrier properties
Foil laminate offers the highest moisture and oxygen barrier, which matters most for concentrate pouches and any format with a longer intended shelf life. Kraft and compostable substrates are available, but they carry lower barrier ratings. If your brand has a genuine sustainability positioning, a compostable option may be worth the trade-off; just be clear about the shelf-life implications before committing. The wrong call here tends to surface at the worst possible time.
Seal integrity
Liquid-adjacent products need a clean, consistent heat seal around the entire perimeter of the bag. This is worth discussing explicitly with your printer rather than assuming it’s covered as standard. Ask about seal width and strength for the specific substrate you’re considering.
Resealable zip
Useful for concentrate pouches, where customers are likely to use the product across multiple servings. Less important for single-serve steep bags, which are single-use. If you’re unsure, ask yourself how a customer will actually interact with the bag once they open it.
One-way degassing valve
Standard for freshly roasted whole beans and ground coffee because they off-gas CO₂ after roasting. Cold brew products don’t have this requirement. A degassing valve is worth paying for when it’s relevant; for cold brew packaging, it generally isn’t. Leaving it off also keeps the bag cleaner and lowers the per-unit cost.
Worth knowing: the features that matter for cold brew packaging are not the same features your roasted coffee bags were built around. A good printer will ask the right questions. If they don’t, that’s a signal worth paying attention to.
Short-run printing lets you test before you commit
Most roasters adding cold brew to their range are testing the market. It’s a new SKU, potentially a new customer, and it’s not yet clear whether it’ll become a permanent part of the range or a seasonal offering.
Short-run digital printing is the practical answer to that uncertainty. Rather than committing to thousands of units of a particular bag format, you can produce a smaller quantity, get the product in front of customers, and gather real feedback before you decide on volume. CBF’s short-run digital printing service exists specifically for this kind of situation.
The process runs like this:
- Settle on your format (steep bag, concentrate pouch, size) and the features you need.
- Choose your substrate. Talk to your printer about barrier rating and shelf life for each option. Get this in writing if you can.
- Sort your artwork. Supply print-ready files or work with a designer who understands packaging specifications. Cut corners here, and it shows.
- Order short-run. Get the product to market while demand is still forming.
- Scale once you know the format works and the customer response justifies it.
A short-run approach keeps cash flow sensible and gives you room to refine the packaging before it becomes a fixed cost.
What well-packaged cold brew actually delivers
The Australian cold brew market has grown steadily over the past several years, led by specialty coffee buyers who are already visually literate and quick to read quality signals from packaging.
A well-specified cold brew bag does a few things at once. It protects the product, which is the baseline. It also communicates something about the roaster behind it. A foil laminate pouch with clean print and considered design reads as a considered product. A bag that looks rushed puts a question mark over everything inside it.
For a roaster entering the cold brew category for the first time, the packaging is often the first thing a new customer encounters. A subscription box opener, a café buyer reviewing samples, a retail buyer scanning a shelf: they all make a judgment before the product is opened.
Good packaging earns the product a fair chance.
